Carlos Tevez's adviser expects the Manchester City striker to be available for this weekend's match against Chelsea.
The Argentina international has been in his homeland for more than a week after his wife gave birth prematurely.
With Vanesa now out of hospital, although the baby is still in intensive care, City boss Mancini wants Tevez back in England.
Mancini revealed after yesterday's goalless draw with Liverpool that he did not know when the 26-year-old would return from compassionate leave, having spoken to the striker three days ago.
City travel to Stoke on Wednesday for an FA Cup replay, then take on Barclays Premier League leaders Chelsea on Saturday lunchtime.
However, Kia Joorabchian today said he believes Tevez will be fit for the Stamford Bridge contest - and refuted claims the player was not keeping his employers in the picture.
Joorabchian told Sky Sports News: "The club have been informed on a daily basis - Carlos Tevez has given 100% to the club since the day he arrived.
"When your child is in intensive care it's a very serious matter.
"He hopes to be back for the Chelsea game. He hopes things will get better, for his daughter's sake and because he wants to get back and play. He loves to play.
"When these things happen you have to deal with them. Obviously he's having to go through a very difficult period but he's dealt with them before and will continue to do so."
Joorabchian continued: "The signs are very positive in terms of his daughter's recovery and we are all hoping this is the case.
"He was determined to get back for the Liverpool game but unfortunately the situation didn't get much better. However, she has got better over the weekend."
Joorabchian insists the information should not be news to City, adding: "He has been keeping the club informed on a daily basis - including the manager...they have exchanged messages once or twice."
And Joorabchian insisted the player is maintaining his fitness while he is in his homeland, as he explained: "He's training daily with the national team of Argentina out there and spending one-and-a-half to two hours there.
"He is a professional. He understands that side of it."
